EVINDOVf-SCREEN VENTLATOR.

Application alsav Deember 5, 1925.

To all w/tom t may concer/n.'

lBe it known that I, ,lnvrNo HUDsoN, a citiates, residing at llfillresof Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in lVindow-Screen Ventilatore, of which the following is a specification, reference being had to the accompanying drawings.

' This invention relates to window screen ventilators andV it is an object of the invention to provide a device of this `kind which, when in applied positioino'tfers no hindrance or obstruction to the desired sliding' movement of the window sash and which is constructed in a manner to permit it to be adjusted to be properly applied to window frames of various widths.

Another object of the invention is to provide a device of this kind constructed in a also be employed to properly diffuse within the room the desired disinfectant or fumigant or to meisten the air passing through the device.

An additional object of the invention is to provide a device of this hind with means whereby it may be effectively maintained in applied or working position and wherein such retaining means is particularly adapted or coaction with the parting strips of the window frame.

rlhe invention consists in the details of' construction and in the combination and arrangement of the several parts of my improved window screen ventilator whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely clarinet,

invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein igure l is a view in outside elevation of a window screen ventilator constructed in accordance with an embodiment of my invention and in applied position;

`Figure 2 is a view in perspective of one ofthe sections of the improved device as herein disclosed; Y

Figure 3 is a view in perspective of the second section 'of' the device as herein employed;

' In order that my and B of substantially veach of the sections A and Serial No. 73,498.

lFigure d is an enlarged vertical sectional y view taken substantially on the line -l-el of Figure l;

.Figure 5 is a view in topplan of the device 1n applied position, portions of the win'- dow frame being in section. Y

My improved window screen ventilator, as herein disclosed, comprises two sections A duplicate construction except that one of the sections, as A, is made in a manner to be readily telescoped within the section B.

Each of the sections A and B comprises an outer vertical wall l having its major' portion cut out, as at 2, and over which is disposed the screen fabric 3 of desired mesh. rEhis fabric 3 may be held in applied position in any desired manner, but as is par. tieularly illustrated in F igure /l the marginal portions of the fabric are clamped between the reverted Hanges l disposed in` wardly of the wall l and defining the cut out portion or opening 2.

,txtending inwardly and upwardly from the lower margin of the wall l on a predetermined curvature is the inner wall 5, the y walls l and 5 being preferably formed from a single sheet of material. The outer end of B is closed by an end plate 6 soldered or otherwise maintained in desired assembled relation.

The outer' end of each of the sections A and B is continued by an outstanding flange 7 which is adapted to lit snugly along the inner face of an outer parting strip 8 comprised in the window frame structure F, Y

the outer margin of'said frame being provided with a lip 9 which is adapted to be engaged between the parting` strip 8 and the adjacent window Iiamb l0.

Each of the sections A and B has the upper marginal portions of its walls l and 5 turned over to provide therealong the tubes or barrels ll 'and l2. It is to be noted that the tube or barrel ll carried by the wall l of each of the sections is inwardly disposed while the tube or barrel l2 carried by the wall 5 of'each of the sections is outwardly disposed. rlhis arrangement is such so that these tubes or barrels of one of the sections', as A, may be readily received within the correspondingbarrels of the second section B and to facilitate this interengagement, the lowerportion of the'barrel 1l carried by the section B is open to provide a slot ll while the lower portion of the tube or barrel l2 of the section A is provided there-along with a slot 15.

ln practicej adapted to he that they iii-a3' nioved in order v'avitational ineens tor inaintaininf-f' the assenillled device in desired position wnhin the window' traine, However. ln' Al'orchg h lips 9 of' the tlanfre" T hetween the pai-tinu .strips S and the il nhs l0. the device is di'eeiivelv maintained in pla 'e However. should it lie preferred5 tacs or the llilte niay lie employed in connection with each ot' the tianees to provide a more po attachment and itor tnis purpose the up \r and lower portiers et lach are provided vith the open- 3L ot the tiang'es ings lt.

lllhen the d vice is applied, as is particularlv illustrated in TFigure 5, it will he readilv observed that it offers no hindrance or obstruction to the desired raising or lowere' ot the lower sich S and also it will he '5, idersiood that t sash S niav lie eiiiplojvfed to control the afl ssion ot air through the screen 'fabrics 3.

i' niarr'iral The lov-:e Y portion ot' the wall l ot each ot the sections has produced therealonp; the o'ieninejs ll to provide drainage 'tor an;v wl ter which may lie collected within he device and to avoid corrosion it is prerred that the various walls ot the sect-ions ud the screen tahric he torined of non-rustinaterial.

The lower portion ot the wall 5 ot each ot the sections and E is adapted to have rested thereon pan l) ot desired capacity and in which inav lie placed water when it is desired to nioisten the air as it enters the rooni or a suitalile disinfectant or tuniigant ine-.js he used.

To further 'taeilitate the pos tioning ot the device within the 'window jLaine, the lower portions ot the ilane'es 'T are continued hy the depending extension lips 1S which overlie "l ce of the window sill ll".

cae outer 'lher-e lips 18 are particularly eipiective in init ailj.' positioning' the device in place.

is to lie noted that the walls 5 ot the section.' extend aliove the openings in the r ells l Thi" assures the air passingI within upward course.

description it is D rooin in an Frein the foregoing;

thought to lie olivious that a window screen ventilator constructed in accordance with inj; invention is iLiart-icularly well adapted 'tor use liv reason oi the convenience and facility with which it niay he assenihied and operated, and it will also lle ohvious that n'rv4 'i vention is susceptible ot sonic change and nioditication without departing; troni the principles and spirit thereof and tor this reason l do not .'isli to lie uiulerstood as limiting' nivselif to the precise arrangl'enient and formation ot the :several parts herein shov'n in carrying iut inv invention in pra-:- tice except as hereinatter claiined.
